/*
  Analog input, analog output, serial output

  Reads an analog input pin, maps the result to a range from 0 to 255 and uses
  the result to set the pulse width modulation (PWM) of an output pin.
  Also prints the results to the Serial Monitor.

  The circuit:
  - Jostick VERT connected to analog pin A0.
    Joystick HORZ connected to analog pin A1.
    VCC and GND of the Joystick go to +5V and ground
    5V relay module 1 SIG is connected to output Pin 0
  - 5V relay module 2 SIG is connected to output Pin 1
